Answer:

It will take Josie 80 minutes to run 10 miles.

Step-by-step explanation:

We can set up a proportion between the number of minutes she runs to the number of miles she runs. From what we know in the equation, we know that it takes her 24 minutes to run 3 miles, and it takes x minutes to run 10 miles. We can represent this in a proportion!

We know that the ratio of 24:3 will be the same for any number of miles, so we can say

\frac{24}{3} =\frac{x}{10\\}

We can solve this by first simplifying the left hand side then isolation x by multiple both sides of the equation by 10.

24/3 = 8

8 = \frac{x}{10}

80 = x

It will take Josie 80 minutes to run 10 miles.

Sora was given two data sets, one without an outlier and one with an outlier. Data without an outlier: 108, 113, 105, 118, 124,
gladu [14]

The outlier (61) is at the low end of the data set, but doesn't affect the mean by a lot, so ...

The mean is centered among the other numbers in both sets of data.

_____

The mean without the outlier is 114. With the outlier, it is 107.4. The lower quartile is 108, so the mean does get moved outside the "box" of the box-and-whisker plot of the data set without the outlier.

Find the equation of the line passing through the point (6,3) that is perpendicular to the line 4x−5y=−10.
Paul [167]

Step-by-step explanation:

( y = 4x/5 + 2)

m1.m2 = -1

4/5.m2 = -1

m2 = -5/4

formula = y - y1 = m2 ( x - x1)

y - 3 = -5/4 ( x - 6)

y -3 = -5x /4 + 30/4

y = -5x /4 + 21/2
